Objectives • Identify compatibilities and define methods for data standardization. • Recommend a forest health monitoring regime to address monitoring gaps. • Identify data format requirements for inclusion into the National Forest Pest Information System.
Data standardizaton: Previous Conclusions • Developing national ground plot standards for collecting and reporting data are not appropriate due to differences in pest behavior, host types, etc. Outstanding Tasks • Develop algorithms to convert ground plot data into a common reporting format in collaboration with IIM • Update monitoring matrix with new information (ex. lure formulation) and update compatibilities.
Data Standardization Standardization of aerial survey categories ?
Data Standardization Standardization of pest codes and host species codes ? • Only a few provinces have pest codes (BC 3 letter codes) ex. IDW = Insect, Defoliator, Western spruce budworm could be expanded to 4 letters to accommodate hardwoods IDCW = Insect, Defoliator, Conifer, Western spruce budworm IDHF = Insect, Defoliator, Hardwood, Forest tent caterpillar • Host species coding • Presently no consistency between provinces • 2001 CANFI numeric coding ? • 2006 NFI coding – genus + species ?
Forest Health Monitoring regime • Collected data required to identify monitoring gaps: • Information on location of monitoring plots, type of plots (PSS or PSP), MFD sampled, and monitoring frequency. • Information on spatial extent of aerial surveys. • Participation by all Provinces and the Yukon • Data in shapefiles, Access or Excel • Cross-referenced with monitoring matrix • Imported into ArcMap and geodatabase
Ground Monitoring Summary • Some P/T’s submitted data spanning a number of years
Ground Monitoring Summary 1 Some may be assessed annually but are not considered annual plots. * Yukon did not report any monitoring sites

How well are we monitoring our 'forests'? • Forest as defined by Canadian National Forest Inventory 2001 is a CANFI cell where forested land is the dominant feature.
Ground Monitoring
How well are we monitoring at an ecosystem-level? • NFPS - ecosystem-based reporting • Ecozones somewhat similar to Forest Regions of Canada • Ecozones as defined by the National Ecological Framework for Canada are: “ an area of the earth’s surface representative of large and very generalized ecological units characterized by interactive and adjusting abiotic and biotic factors.” • Ecozones used in NFI stratification
Ground monitoring (annual and variable) summary by Forested portions of Ecozones
Monitoring Summary • Gaps in Northern Canada and urban areas • Low percentage of plots monitored annually • Majority of ground monitoring plots are pest specific; very few at an ecosystem or forest type level ex. CIPHA. • Although some ecozones appear adequately monitored (proportional representation) the spatial distribution may not be adequate.
Moving Forward • What attributes should be collected in the better and best scenario ground plots? • Fixed radius plots? No tagging. • Is remote sensing a feasible and reliable option for remote areas? • northern Canada predicted to have greatest warming due to climate change • For the best scenario how do we stratify the landbase? Ex. proportional by ? (forest type, ecozone, host species)
